Subject: ANNOUNCE: mdadm 2.1 - A tool for managing Soft RAID under Linux I am pleased to announce the availability of mdadm version 2.1 It is available at the usual places: http://www.cse.unsw.edu.au/~neilb/source/mdadm/ and http://www.{countrycode}.kernel.org/pub/linux/utils/raid/mdadm/ mdadm is a tool for creating, managing and monitoring device arrays using the "md" driver in Linux, also known as Software RAID arrays. Release 2.1 fixes a few problems found after the release of 2.0. If you are using raid10 or version-1 superblocks and upgrade is recommended. Specifically: - Fix assembling of raid10 array when devices are missing. mdadm now correctly detects if a array is workable or not depending on which devices are present, and so will correctly handle "--assemble --force" if multiple devices have failed. - Report raid10 layout in --examine output. - Fix assembling of arrays that use the version-1 superblock and have spares. Previously the spares would be ignored. - Fix bug so that multiple drives can be re-added at once. - Fix problem with hot-adding a bitmap to version-1-superblock arrays. Development of mdadm is sponsored by SUSE Labs, Novell Inc. NeilBrown 12th September 2005
